DUAL-T1msn TRUCK WHEEL.

Application led November To allwhomz't may concern'.l Beit known that LLLoYD D. KAY, a citizen of the United States, residing at Los Angeles, in-the county of Los Angeles and State of California, have invented a new and useful Dual-Tired Truck Wheel, of which the following is a speciiication.

This invention, relates to wheels such as type of truck wheel that carries two tires.

As usuali constructed such a truck wheel has a wide elloe and the two tires are mounted on the same felloe side by side with a separator ring between them( This arrangement is not adapted to pneumatic tires and .Alias other objections.

l The general object of this invention is to produce a wheel of this type which isl light in weight but so constructed that it will have ample strength in service, and in which the tires can be readily put in place, the iniiatin nipples being easily accessible to enable t e tires to be iniated.

Further objects of the invention will appear hereinafter:

The invention consists in the novel parts and combination of parts to be described hereinafter, all lof which contribute to pro- "3o. duce an eiiicient dual tired truck wheel.

A' preferred embodiment of the invention is described in .the following specification while the broad vscope ofthe invention is Y pointed out in the appended claims.

In the drawings:

. Fig. lis a front elevation of a wheel embodying my invention'.A

Fig. 2 is a vertical section through the rim fof the wheel and through the tires adjacent theiry inflating nipples,and upon an enlarged scale.

Fig.` 3 is a section vtaken about on the line 3-3 of Fig. 2 looking in the direction of the arrow 'but -upon ansmaller scale, and with the tires omitted.

Fig.; 4' is'a'section taken the same plane i as the liner3`-3 but .looking in, instead of out, that is-tosay,plooking oppositely to the V'direction indicated by the arrows; and this viewl is uponl 'asmaller scale.

5' is a typical section through the edge orfrim ofthelwheel'on thesame scale as Fig.

mnd Fig. 6 is a fragmentary section on the -i Thsjfwheel is intended toi'be constructed ofcastfsteel'or castjironiA '4 l; Itfcomprises a hub I of any `suitable con- 13, 192.3. Serial N0. 674,476.

7, the latter of which is displaced outwardly beyond the plane of the drum. j

The spokes are connected together by a. web 8, which .also connects the adjacent edges of the felloes with each other; said web being preferably in the form of an arch concave on its outer side and convex on its inner side. This arch at4 the lower side of the wheel, which receives and transmits the 'ground forces to the hub, gives the wheel great strength and effectively prevents breaking of the felloes from the wheel body. In order to lighten the weight without substantially detractin from the strength, this web is provided wit equidistant openings 9.

The spokes 5 are substantially `ilat arms 'with the flat disposed substantially in the radial plane of the wheel.

On the felloes 6 and 7 two tirerims 10 and 11 are carried. The'twofelloes 6 and 7 `are separate and distinct from eachother,- and support therims 10 and 11 so that there a key-ring seat 13 of smaller diameter but also of conical form. The rim` 10 has a conical face `14 to rest onthe seat 12 and has a conical face 15 to lie opposite and cooperate with the key-ring seat 13. This enables a wedge shaped key-ring 16 to be shoved into place between the faces 13 and 15, and whenthis ring is tightened home by means .of boltsf17 and lugs 18, the inner rim 10 will be securelywlheld in place. To facilitate putting this lfiey-ring 16 in place, it is preferably `constructed in the form of a split ring. I A

To carry the outer rim 11, I provide a Xed key-ring 19 mounted' on a conical seat 20 on the inner edge of the outer felloe 7,

' a plurality of spokes, each spoke consisting i To facilitate putting it in place the vring 19 is made in two halves or in sections.

The outer edge of the felloe 7 has a conical seat 25 Vlying opposite to a cooperating conical face 26 on the under side of the rim 11 and in the space between these faces is received a wedge shaped key-ring 27,

` held in place by bolts 28 and lugs 29.

The pneumatic tires 30 may be mounted v0n their rims in any suitable way.

In attaching the rims, of course the inner rim is put in place first, the key-ring 16 put in place, and the bolts 17 tightened up lThe felloe 7 is of smaller diameter than'the seat 12 so as to permit the inner rim to pass over it freely..

After the-inner rim-is in place, the fixed key-ring 19 is put in place, the outer rim 1l put in place, and the key ring 27 is wedged up home by tighteningl the bolts 28 upon the lugs 29.

Wlthfa Wheel having the features of construction of my invention the bolt heads are readily accessible to a Wrench.

In order to render the iniatng nipples 3l of the tires accessible, I provide the web 8 with a large gap' or opening 32 adjacent the nipples.

It is understood the invention. described herein is only one of the many embodiments this invention may take and I do not Wish to be limited in the 4practice'of my invention nor in my claims to the particular embodiment set.

`fort/l1.' l K What I claim is: l 1. A' motor truck wheel having a hub with Athat the embodiment of of an arm disposed in a plane extending radially from thev axis of the Wheel, a felloe extending continuously, connecting the ends of the arms and disposed in a plane displaced laterally from the hub, a second felloe connected With the said spokes. and sup#V ported thereby and disposed substantially f axis ofthe Wheel, an outer felloe extending I continuously around the wheel connecting the ends of the arms and disposed in a plane displaced laterally from the hub, an inner felloe distinct from and separated from the outer felloe, connected With the said spokes, supported thereby and disposed substantially in the plane of the hub, said felloes having seats for securing tire rims thereto. 3. A motor truck Wheel for dual tires, having a hub with a plurality of substantially radial spokes extending'from the hub, an outer felloe constructed to operate as a rim seat, an inner felloe constructed to operate as a rim seat distinct from and separate from the outer elloe, and' a' Web.connecting the felloes, said web 'bein disposed in an arch concave on itsouter si e and convex on its inner side.
